HUTCSS COMP t AThis invention relates to new and useful i" Ayimpro/vefnients :iny tacking machines such as f1 ,l are used for securing dlrection or other labels toship ingy hoxe's, and like uses. lijfje ject lof the invention is to provide a machinewfor vthepurpose stated which ma l i chine Operable in the fashion of a hammer,

fthe machine carrying a strip of staples which are: automatically fed forward to be used l feta leor tack.

@j .i nother object of the invention is to provide a tacking machine ofthe character stated the same being so constructed that after a slight adjustment, the machine may be used as an ordinary hammer. v

Other objects and'advantages will become apparent from a consideration of the followc Qing detailed description taken in connection .with the accompanying drawin showing one embodiment of the invention. hile the invention is shown and will be. described. in de tail, it is to he understood that changes 1n construction, combination and arrangement oir' parts may be made without departing from the spirit of the invention or the scope'of the aPpended claims. 1^ 'f In the drawing: i i 'f5-' Fig. 1 is a side elevational view of the com? plete i machine, parts being broken 'away .t0

" "more clearly illustrate the details of construe-'j v erably of the substantially one at a time, each time the machine is .forcefully brought into engagement with .the oh- 'ject into which it is desired to drive the ,1 or nonwanu, commencer, a conronarrou or oorvnnurr posed thereon, the latter being used one at a, time to be driven by the plunger, and the strip being fed forwardly along the guide bar b means of a follower 15. The staples are pre U-shaped type.

Follower 15 is substantially U-shaped iu section and straddles the guide bar 13 whereby its front end will be in engagement with the last staple of the strip, the stri also being U-shaped and straddling the guide bar. In its upper surface the Afollower 15 is provided with a small elongated opening 16 through vwhich is hooked a stud l? carried by a button or finger piece 18. To the iece'l 1s secured one end of a flat spring 19 t e other l a cross member,

end of which is secured to or rivet 20 in the housing, the s ring being wound about the rivet 20 as clear y shown in the dotted lines in Fig. 1. As will be understood the tendency of the spring is to "wind itself up and due to this tendency the follower is drawn along'the guide bar 13 feeding the strip 14 up to. bring the individual staples successiveplunger.

mer head 23 secured to its upper end by any suitable meansas by pin 24C. Within 'the housing 10, the stem 21 is hollow and discof forwardly as it is used n ly one at a time to driving position under the .i

A stem 21 carrying aplunger 22 has a ham-` posed within the stem is a coil spring 25 wh1ch-fw1th`a flat spring 26 secured to the shank at 27 and engaging the under side oi? the hammer head as at 28, serves to normally I, plunger 22 in elevated position as shown in f Figs: 2 and 3. `.Either one of the springs may j f, -j be dispensed with if desired but two springs proper operaw f. .thilaaerihnnim dlmvn viinamadlaml' n maintain the hammer head,.stem 21 land are preferably used to insure tion f Y action of the springs to force the plunger 22 to engage the first staple on the strip 14 carrying said staple downwardly in the guide 'way between vthe portion 29 and the forward end of the shank 11 to embed thesame in the object suggested in Fig. 1 and designated 30 such as a shipping box and the tag or label to be secured thereto indicated at In other words every blow will automatically set a'staple through operation of the plunger by the momentum of the weighted head 23, and

no hand or other operation of the plunger is required.

It is sometimes desirable to use the machin or tool as an ordinary hammer andl to this end means are provided whereby on a slight adjustment being made the device may be used as an ordinary hammer, the head 23 to this end being provided with a striking surface 31, and if desired may also have claws 31". To the head 23, forwardly of the hous-x ranged within the stud 34. As suggested in Fig. 1 the pawl 36 has two positions, one being against the outer face of the member 32 as shown in full lines and the other being within the slot 33 with the end 39 of the pawl in engagement with the lower end 33a of the slot 33 in the member 32. In this latter position wherein the pawl is shown in dottedv lines, the pawl will act to maintain the hammer head 23 in its depressed or lowermost position as shown in Fig. 1. When the parts are in this position the inner end of the stem 21 will be abutting a stop or limiting means or block 40, and further inward movement of the stem will be prevented by this stop means.

When the hammer head 23 is held depressed .against the action of the springs 25 and 26 the plunger 22 is of course, also, held depressed and the machine may be used as a ammer either to drive tacks or other uses for which a hammer is ordinarily employed. The claw portion 31 may have one claw longer than the other as shown so that if the staple to be drawn happens to be too narrow to receive both claws one only, the longer one, may be inserted under the bar of the staple to remove it. The claw portion may be used for removing tacks, nails and the like the same as the usual claw on a hammer. Since the plunger 22 is held .depressed it will prevent additional staples o'f the strip 14 from being fed forward into position for use and it will not reciprocate up and downwardly to eject them from the machine. Also, it is to be noted that the end of the stem 21 has entered the housing 10 as far as possible and being held in this position with the end of its stem in engagement with the stop 40 a rigid hammer construction is provided.

'Ifo have the device again act as a tacking machine for automatically driving staples, it is but necessary to swing the pawl 36 from the dotted line position of Fig. l to the full line position thereof. To again change the device into a hammer it is but necessary to hold the parts depressed and swing the pawl 36 from the full line position of F 1g. 1 to the dotted line position thereof with its free end against the shoulder 33.
